Hello everyone
We are building a townhouse to KfW 55 standard. So far, we have planned to use conventional radiators, as we find their response time better. However, doubts are now arising about whether these radiators can even be used in a KfW 55 building or if there are any reasons against it.
Has anyone dealt with this or is knowledgeable about it here?
We are not fans of underfloor heating, but if there is no other technical option and someone can explain why, we would consider using it as a last resort.

To build on ypg’s thoughts, I’m wondering if this is technically feasible at all. KFW55 sounds strongly like a heat pump. Can these even provide the necessary flow temperature for a conventional heating system? I had always assumed that the energy source and the heating elements (for example, heat pump and underfloor heating) need to be considered as a system...?!

The important question was whether the KfW 55 standard can be met despite using radiators. This has now been confirmed.
Although underfloor heating would save us about 12% more on heating costs, it doesn’t justify the additional expenses.
For us personally, underfloor heating has more drawbacks than benefits, including health-related ones.
Nonetheless, thank you for your opinions.
For us, the next step is now the architect.
